After doing some rescue exercises we went down for another dive moving the other way along the wall. It wasn't as colourful as the previous dive, but there were plenty of docile fish. Came across a second little bit of wreckage which may have been part of the Portland Dredger or a separate wreck. I lost Graham and Simon for a short while towards the end of the dive but fortunately spotted the glimmering of Graham's torch and swam towards it showing the 'OK' signal. Got a bit of a telling off from the skipper when we got back because he had been told we would only be gone 45 minutes and we were gone an hour and a half including all the towing. Unfortunately no-one had told us we were only supposed to be gone 45 minutes.
